[coreboot] Proposing a change to Coding Style

[Patrick Georgi]

Hi everybody,

after just running into an issue on the EC code base, I hereby propose that
going forward, we should always wrap conditional blocks in braces, even
one-liners.
That is:

if (foo) {
   bar();
}

instead of

if (foo)
   bar();

It doesn't hurt too much but saves us from accidentally adding baz() after
bar(), forgetting to add the - now required - braces. If we get rough
consensus over this, I'd change Coding_Style to match.

Thoughts?
